Zusammenfassung:	The invention relates to a recycling method of vanadium, in particular to a method for efficiently recycling vanadium in vanadium-containing underflow slag. The method includes the steps of a, adding vanadium liquid with the vanadium concentration being 10-30 g.L into vanadium-containing clinkers, mixing the vanadium liquid with the vanadium-containing clinkers, carrying out leaching for the first time and obtaining vanadium-containing clinker alkaline-leaching slurry; b, mixing vanadium-containing underflow slag slurry with the vanadium-containing clinker alkaline-leaching slurry according to the mass ratio of 1 to 1-3, carrying out grinding and soaking and obtaining mixed slurry; c, carrying out suction filtration on the mixed slurry and obtaining vanadium liquid and filtration residues, wherein the vanadium liquid is used for preparing ammonium polyvanadate; and d, mixing the filtration residues with water and carrying out leaching for the second time. The method has the advantages that the reactivity
